For a purpose of convenience of description, thewearable electronic apparatus, such as the smart watch, will beexemplified for the depiction hereinafter.

FIGS. 1A to 1C are structural block diagrams illustrating the electronicapparatus in accordance with the embodiment of the disclosure. Theelectronic apparatus 100 in accordance with the embodiment of thedisclosure comprises a body device (which also can be referred to asbody or main body) 101 and a holding device 102, as shown in FIGS. 1A to1C. The holding device 102 is connected with the body device 101, andthe holding device 101 is used to fix a relative position relationshipwith respect to a user of the electronic apparatus, among others. Theholding device 102 comprises at least one holding state in which theholding device 102 can be one annular space or at least part of anapproximated annular space compliant with a first predeterminedcondition, and the annular or the approximated annular space can enclosea periphery of a cylinder compliant with a second predeterminedcondition.

The first to fourth example configurations of the holding device will bedepicted with further reference to FIGS. 2A to 2D hereinafter. In FIGS.2A to 2D, for a simplicity and clearance of description, only the bodydevice 101 and the holding device 102 in the electronic apparatus 100are shown.

Particularly, FIGS. 2A and 2B illustrate two holding states in which theholding apparatus 102 is connected with the body device 101,respectively. A closed-loop annular space is formed by the holdingdevice 102 and the body device 101 in a first holding state as shown inFIG. 2A, and wherein parts of the annular space are constructed by theholding device 102 and the body device 101 respectively. An approximatedannular space with a small opening is formed by the holding device 102and the body device 101 in a second holding state as shown in FIG. 2B,and wherein parts of the annular space are constructed by the holdingdevice 102 and the body device 101 respectively. In one embodiment ofthe disclosure, the body device 101 is a dial portion of the smartwatch, and the holding device 102 is a strap portion of the smart watch.The annular or the approximated annular space formed by the body device101 and the holding device 102 can enclose a periphery of a wrist of auser which is the cylinder, and a diameter of the annular or theapproximated annular space is greater than that of the wrist of the userand less than that of the fists thereof.

Moreover, the annular or the approximated annular space may surely beformed by the holding device 102 individually. The body device 101 maybe arranged on the holding device 102, i.e., the body device 101 isattached to the holding device 102 in a surface contact manner, suchthat the annular space (FIG. 2C) or the approximated annular space (FIG.2D) for enclosing the cylinder is merely formed by the holding device102 itself, as shown in FIGS. 2C and 2D. The holding device 102 isprovided with a holding mechanism (not shown), such as an agrafe, asnap, a zip, and the like.

Returning to FIGS. 1A to 1C, the configuration of the electronicapparatus 100 is further depicted.

More particularly, a processing unit 103 and a first display unit 104are arranged on the body device 101, as shown in FIGS. 1A to 1C. Theprocessing unit 103 is utilized to generate an image to be displayed andperform a display control. The first display unit 104 is utilized tooutput a first image. More particularly, the first image generated bythe processing unit 103 is output by the first display unit 104 underthe display control performed by the processing unit 103. The firstdisplay unit 104 is arranged on the body device 101 in the electronicapparatus 100 shown in FIGS. 1A and 1C. However, it is appreciatedreadily by those skilled in the art that the disclosure is not limitedthereto. For example, the first display unit 104 may also be arranged onthe holding device 102 in the electronic apparatus 100 shown in FIG. 1B.

The first display unit 104 is a display unit complying with variousdisplay principles. For example, the first display unit 104 may be anear-to-eye optical (e.g., LOE (Light-guide Optical Element)) displaysystem.

More particularly, the first display unit 104 may comprise a firstvisible portion 1041 which is a portion viewed by the user so as toperceive or see a displayed content in the first display unit 104. Thatis, the first display unit 104 as described below contains a pluralityof members depending on the principle thereof, and wherein a firstvisible portion 1041 is a region in which a display of the image contentis observed actually by the user. At this point, a position of the firstdisplay unit 104 as described above may in fact refer to the position ofthe first visible portion 1041.

The principle and implementation of the first display unit 104 will bedescribed particularly with reference to FIGS. 3A to 3D and FIGS. 4A to4C hereinafter.

FIG. 3A is the principle diagram illustrating the near-to-eye opticaldisplay system employed in the electronic apparatus in accordance withthe embodiment of the disclosure. The near-to-eye optical display systemis employed to be the first display unit 104 in the electronic apparatusin accordance with the embodiment of the disclosure. The light emittedby a micro display unit 201 in the near-to-eye optical display systemcorresponding to the image displayed thereby is received via an opticalcomponent 202, such as a group of lenses, and subjected to an opticalpath conversion accordingly, as shown in FIG. 3A. As a result, the lightafter the optical path conversion enters into the pupils 203 of theviewer and forms an enlarged virtual image.

FIGS. 3B to 3D further illustrate three particular implementations basedon the principle diagram of FIG. 2A. Particularly, a design ofrefractive-diffractive hybrid curved surface is employed in the solutionillustrated in FIG. 3B, wherein a group of lenses 204 corresponds to theoptical component 202 as shown in FIG. 3A, such that the volumesrequired for the lenses are reduced. The solution as shown in FIG. 3Cemploys a design of free form curved surface in which a group of freeform curved surface lenses 205 comprising the curved surfaces 1, 2, and3 corresponds to the optical component 202 as shown in FIG. 3A, suchthat the volumes required for the lenses are further reduced. Thesolution illustrated in FIG. 3D employs a design of parallel panel inwhich an optical waveguide plate 207 is included in addition to thegroup of lenses 206 corresponding to the optical component 202 as shownin FIG. 3A. In a case where a required thickness of the lens is reduced,a control, such as a translation, for an exit direction of the light forforming an enlarged virtual image, i.e., a display direction of theenlarged virtual image, is conducted by utilizing the optical waveguideplate 207. It is understood readily by those skilled in the art that thenear-to-eye optical display system employed in the electronic apparatusin accordance with the embodiment of the disclosure is not limited tothose as shown in FIGS. 3B to 3D above, and other implementations, suchas a design of projection eye lens, may also be employed.

FIGS. 4A to 4C are schematic diagrams illustrating the display unit inthe electronic apparatus in accordance with the embodiment of thedisclosure. The near-to-eye optical display system described withreference to FIG. 3 is employed by the first display unit 104 in theelectronic apparatus 100 in accordance with the embodiment of thedisclosure. The first display unit 104 comprises a first displaycomponent 301 for displaying a first image and a first optical component302 (a first optical components 302A to 302C in FIGS. 4A to 4C) forreceiving the light corresponding to the first image emitted by thefirst display component 301, and for performing the optical pathconversion on the light corresponding to the first image, in order toform the enlarged virtual image corresponding to the first image.

Particularly, in FIG. 4A, the first display component 301 may be a microdisplay, and the first optical component 302A is formed by a group oflenses. The enlarged virtual image corresponding to the first imagedisplayed by the first display component 301 is formed by such group oflenses.

In FIG. 4B, the first display component 301 may also be a micro display,and the first optical component 302B is formed by an optical deviceconducting multiple reflections in the apparatus. In that case, a sizeof a space required for the first display unit 104 may be saved, ascompared with the first optical component 302A as shown in FIG. 3A, suchthat it is convenient for a design and manufacture of a more miniatureelectronic apparatus.

In FIG. 4C, the first display component 301 may also be a micro displayas well, and the first optical component 302C is formed by a group ofzooming lenses performing in-and-out zooming under a drive by a driveunit (not shown) within the apparatus. In that case, the size of theenlarged virtual image displayed by the first display unit 104 may beadjusted dynamically by zooming, as compared with the first opticalcomponent 302A, such that different requirements of the users aresatisfied.

The region in which the display of the image content by the firstdisplay unit 104 is observed actually by the user is the first visibleportion 1041 as described above with reference to FIGS. 1A to 1C, asshown in FIGS. 4A to 4C.

In the electronic apparatus 100 as described above with reference toFIGS. 4A to 4C, at least part of the first optical component 302 is acomponent in which a transmittance rate is compliant with apredetermined condition in an outward direction of the annular or theapproximated annular space. At least part of the first optical component302 is a region corresponding to a displayed image upon a display isperformed. More generally, in the outward direction of the annular orthe approximated annular space corresponding to the at least part of thefirst optical component 302, and the transmittance rate of theelectronic apparatus 100 is compliant with the predetermined condition.Particularly, the electronic apparatus 100 corresponds to a portion ofthe optical waveguide plate 207 in the display direction in which the atleast part of the first optical component 302 is the enlarged virtualimage, as shown in FIG. 3D. The transmittance rate of a portion of theoptical waveguide plate 207 observed directly by the eyes of the user iscompliant with the predetermined condition, and the transmittance rateof a portion not observed directly by the eyes of the user, for example,the portion corresponding to the micro display unit 201 and the group oflenses 206 is not necessarily compliant with the predeterminedcondition. The predetermined condition may be that the transmittancerate is greater than or equal to a predetermined value. For example, thepredetermined value may be 30%. The predetermined value may be 70%. Assuch, a skin of the user himself/herself may be observed through theelectronic apparatus 100 by the user.

Returning to FIGS. 1A to 1C, the configuration of the electronicapparatus 100 is further depicted.

More particularly, an acquisition unit 106 is also arranged on the bodydevice 101, as shown in FIGS. 1A to 1C. The processing unit 103 isutilized to perform an acquisition control. The acquisition unit 106 isutilized to acquire a first signal. More particularly, the first signalis acquired by the acquisition unit 106 under the acquisition controlperformed by the processing unit 103. The acquisition unit 106 isarranged on the body device 101 in the electronic apparatus 100 shown inFIG. 1A. However, it is appreciated readily by those skilled in the artthat the disclosure is not limited thereto. For example, the acquisitionunit 106 may also be arranged on the holding device 102 in theelectronic apparatus 100 shown in FIGS. 1B and 1C.

The acquisition unit 106 is a unit working compliant with variousacquisition principles. For example, the acquisition unit 106 maycomprise, but not limited to, a sensing unit, an image capture unit, asound capture unit, a biometric capture unit, and/or a distancedetection unit, etc., for acquiring the same or different type(s) of thefirst signal(s), such that the same or different operation(s) is/areperformed by the electronic apparatus according to the first signal(s).

One or more acquisition units 106 may be set in the electronic apparatus100, and the acquisition units 106 may be set at respective positions onthe electronic apparatus 100.

More particularly, it is apparent that a plurality of acquisition units106 may be set on the body device 101 and/or the holding device 102respectively, when those acquisition units 106 are included in theelectronic apparatus 100.

However, a plurality of individual function modules may also be set onthe body device 101 and/or the holding device 102 respectively, sincethe acquisition unit 106 possibly consists of those function modules,when only one acquisition unit 106 is included in the electronicapparatus 100, that is, such single acquisition unit 106 may also be seton the body device 101 and/or the holding device 102. For example, theacquisition unit 106 may be set on the body device 101 or the holdingdevice 102, if the image capture unit is construed narrowly to comprisemerely the group of lenses, when the acquisition unit 106 is the imagecapture unit, such as a video camera. Conversely, if the image captureunit is construed generally to comprise only the function modules of agroup of lenses, an internal imaging unit, and a shutter button, etc.,apparently, those different function modules may be set on the bodydevice 101 and/or the holding device 102 respectively.

The principle and implementation of the acquisition unit 106 will bedepicted specifically in various embodiments hereinafter.

First Embodiment

In the first embodiment of the disclosure, the acquisition unit 106 maycomprise a sensing unit (which also can be referred to as sensor) forsensing a sense control operation generated by an event that anoperating object touches or near touches a sense region, in order togenerate a first sensing signal. The processing unit 103 generates afirst control signal according to the first sensing signal, and controlsthe electronic apparatus 100 to perform the first control signal.

For example, the sensing unit 106 may be a type of contact sensing unitwhich is an input device for controlling the electronic apparatus 100through a physical contact (a touch operation) above the contact senseregion, e.g., a smooth surface of an operation panel, by an operatingobject, e.g., a finger, a stylus, and so on. For example, the touchsensing unit may be a contact touch panel, and the like. Alternatively,the touch sensing unit may be a contact touch screen, and the like, whenintegrated with a display unit together.

Alternatively, the sensing unit 106 may also be a type of suspensionsensing unit which is an input device for controlling the electronicapparatus 100 through a non-physical contact (a suspension operation) bya distance, e.g., 2 centimeter (cm), from the top of the contact senseregion, e.g., a smooth surface of an operation panel, by an operatingobject, e.g., a finger, a stylus, and so on. For example, the touchsensing unit may be a contact touch panel, and the like. Alternatively,the touch sensing unit may be a non-contact touch screen, and the like,when integrated with a display unit together.

The processing unit 103 may control the electronic apparatus to operatein response to the sense control issued by the user through a mappingrelationship by querying a mapping table, a mapping file, a database,and the like, after the sensing unit 106 operates according to a sensecontrol issued by the user. For example, when the sensing unit 106senses that the user performs a single click operation (in the case ofthe contact sense) or a finger press operation (in the case of thenon-contact sense) on an operation panel, the processing unit 103 maycontrol the electronic apparatus 100 to complete various processescorresponding thereto according to the interactive control operations asdescribed above by the user.

A relative position relationship between the sensing unit 106 and thefirst display unit 104 and/or other units in the electronic apparatus100 may be configured optimally, in order to ensure that the user isable to input the interactive control operation to the electronicapparatus 100 more conveniently and flexibly by using that sensing unit106 while viewing a response to such interactive control operation ofthe electronic apparatus 100 by using the first display unit 104.

For example, a convenient interactive control over the smart watch maybe conducted by a touch control unit above a touch screen, when thesensing unit 106 and the first display unit 104, e.g., a common liquidcrystal screen or an Organic Light-Emitting Diode (OLED) screen, areintegrated with each other to form the touch screen and are arranged onthe dial portion of the smart watch.

A touch unit set on the dial portion of the smart watch may be utilizedto conduct the interactive control, when the first display unit 104 is anear-to-eye display. A common display unit may be turned off,particularly, a touch screen may be used as an absolute or relativeposition control apparatus, when the interactive control is conducted,if the touch unit pertains to the touch screen comprising the commondisplay unit.

The first display unit 104 comprises a first visible portion 1041 whichis a portion viewed by the user so as to perceive or see a displayedcontent thereof in the first display unit, and located at a firstregion, as described above. The sensing unit 106 comprises a senseregion above which the sense control operation generated by theoperating object is sensed by the sensing unit 106.

Particularly, in the former case, the first region and the sense regionmay be the adjacent regions between which there is at least one commonside. That is, the relative position relationship between a displaysurface, i.e., the first region where the first visible portion 1041 islocated, of the first display unit 104, for example, which may be onenear-to-eye display, and the sense region, e.g., a touch surface, of thesensing unit 106, e.g., the touch screen, is adjacent. Moreparticularly, the former case may also include two different situationsas follows.

In the first situation, the first display unit 104 and the sensing unit106 are set concurrently on the holding device 102, e.g., the strapportion of the smart watch, or the first display unit 104 and thesensing unit 106 are set concurrently on the body device 101, e.g., thedial portion of the smart watch, and the first region and the senseregion are on the same plane, as well as the sense region is set on atleast part in a region surrounding around the first region. That is, onthe same plane, the periphery of the first visible portion 1041, e.g.,the display surface of the near-to-eye display, may be enclosed entirelyor partially by the sense region, e.g., the touch surface.

The different configuration examples of the first display unit and thesensing unit in the first situation will be depicted with reference toFIGS. 5A and 5B hereinafter.

FIG. 5A is the top view illustrating a first configuration example ofthe sensing unit of the electronic apparatus in accordance with thefirst embodiment of the disclosure.

In the first configuration example, the first visible portion 1041 andthe sense region are on an external surface of the annular or theapproximated annular space concurrently, and the display direction ofthe first visible portion 1041 is in the outward direction of theannular or the approximated annular space, as well as the first visibleportion 1041 is nested inside at least part of a strip region formed bythe sense region.

For example, the display surface of the near-to-eye display and thetouch surface of the touch screen are both on a frontal region of thedial portion, i.e., a top surface of the dial portion, of the smartwatch, and a frame of the display surface is formed by the touchsurface, so as to enclose the periphery of the display surface entirely,as shown in FIG. 5A. However, it is appreciated readily by those skilledin the art that the disclosure is not limited thereto. For example, thedisplay surface and the touch surface may also be both on the strapportion of the smart watch. Further, a portion in the frame of thedisplay surface may also be formed by the touch surface, so as topartially enclose the periphery of the display surface.

It is stated herein that the term “frame” may means an entity skeleton.That is, a dial skeleton of the smart watch is formed directly from amaterial, e.g., a glass and a metal, etc., constituting the sensingunit. Alternatively, the term “frame” may also means that the sensingunit is formed by an entity skeleton attached to the electronicapparatus. That is, in the case where the dial skeleton of the smartwatch is formed from a plastic, the sensing unit may be fixed on theplastic skeleton through a manner of gluing, clipping, riveting, and soon.

As such, setting a touch sensor on the periphery of the display regionof the smart watch, thereby the problem in which a displayed output willbe impacted when input of touching is performed for the smart watch issolved. The touch sensor may be particularly set at the rim of the frontsurface of the smart watch (the displayed content of one display unitmay at least be viewed in the front surface of the smart watch), asdescribed above. That is, the touch sensor may be set at the dial frameof the smart watch.

More particularly, the touch sensor may be set on one or more sidesaround the smart watch. If the front surface of the smart watch is arectangle, the touch region may be one or more sides, or even cover theentire rectangle. If the face of the smart watch is a circle, the touchregion may be a section of arc, or even cover the entire circle.Apparently, such periphery-enclosed touch operation is comparativelyconvenient and fast, which avoids the problem in which it is prone tocause a misoperation upon inputting by touching due to a small volume ofthe electronic apparatus itself. In addition, an impact on the displayedoutput resulting from the touch input, which is particularly conspicuousin the case where the near-to-eye display unit viewed with a near-to-eyeviewing by the user is required, may be avoided, since the touch regiondoes not overlap with the display region.

FIG. 6A is the first implementation illustrating the sense region of thesensing unit of the electronic apparatus in accordance with theembodiment of the disclosure.

In the first implementation, it is assumed that the front surface of thesmart watch is a rectangle, and the touch region may be two sides of L1and L2, then a specific distribution of the two sides of L1 and L2 hasat least six possibilities with respect to the front surface of therectangle electronic apparatus as shown in FIG. 6A.

FIG. 6B is the second implementation illustrating the sense region ofthe sensing unit of the electronic apparatus in accordance with theembodiment of the disclosure.

In the second implementation, it is assumed that the front surface ofthe smart watch is a circle, and the touch region may be two sections ofarcs of L1 and L2, then a specific distribution of the two sections ofarcs of L1 and L2 has at least six possibilities with respect to thefront surface of the circle electronic apparatus as shown in FIG. 6B.

In both of the above embodiments, for example, the substantial touchactions with respect to the two ends of L1 and L2 of the frame may bedefined as a slide, a single click, a double click, a triple click, along press, and a non-operation, etc.

20 combinations of operations, i.e., corresponding to 20 operationcommands P11, P21-P22, P31-P33, P41-P44, P51-P55, and P61-P65 on whichthe certain execution may be defined by the user himself/herself, may bepermuted and combined through the concurrent touch operations on twooperation lines of L1 and L2, without any distinction of L1 and L2 fromeach other, as shown in Table 1 below.

Several possibilities for the specific distribution of L1 and L2 isshown in Table 1:

Single Double Triple Long Non- L1/L2 Slide Click Click Click Pressoperation Slide P11 Single P21 P22 Click Double P3 P32 P33 Click TripleP41 P42 P43 P44 Click Long P51 P52 P53 P54 P55 Press Non- P61 P62 P63P64 P65 operation

However, it is appreciated readily by those skilled in the art that thedisclosure is not limited thereto. 36 combinations of operations may bepermuted and combined through the concurrent touch operations on twooperation lines of L1 and L2, with a distinction of L1 and L2 from eachother.

Among those 36 combinations of operations, only several optimal touchoperations therein may be chosen in order to avoid the misoperationcaused by the user and make the touch operation of the user to be themost natural and smooth. For example, those optimal touch operations maybe the concurrent sliding in the same or different directions for L1 andL2. For the circle watch, the touch operation as described above is toslide continuously along the arc; for the rectangle watch, the touchoperation as described above is to slide along the segments of the sidesof the rectangle. Moreover, a touch operation may be the operation bywhich L2 is sliding while L1 is long-pressed.

In the case of the rectangle dial, the operation as described above maybe used for a zoom in-and-out, a page up-and-down, and a deletion of thecontent items, and/or an unlock of the entire screen.

In the case of the circle dial, the operation as described above may beused for a launch of program, a setup of location, an unlock of screen,a setup of time, a focusing of camera, an adjustment of volume, and thelike. The detailed specification below may be referred for a purpose ofa convenient appreciation.

For example, it is common that two fingers should press at the circleframe of the watch at 180 degrees upon a compass is used according to ahabit of the user, if a program of the compass is installed in the smartwatch. Therefore, the touch screen may be caused to detect the touchposition and the touch region by the user continuously or at someinterval, and it may be decided that the program of the compass isrequired to be opened by the user when the user has been determined topress at the fame of the watch with two fingers at 180 degrees, then theprogram of the compass is started automatically and immediately for theuse of the user.

Again, for example, the digits for the time may be increased ordecreased through a uni-direction sliding by using one finger in thecircle frame by the user according to the habit of the user, if aprogram of an alarm clock is installed in the smart watch.

Again, for example, two fingers may be pressed at the frame of the watchby the user at some angle concurrently, and a clockwise orcounter-clockwise rotation is conducted, so as to control the camera tozoom, similar to a gesture for the focusing of a common camera withlenses used by the user, if a program of a camera is installed in thesmart watch. This will provide the user with an operation experiencecompliant most with the practice use habit, particularly the zoomingcontrol at the time when the user is viewing through the display unitwhile taking photos.

Again, for example, the circle frame of the smart watch may be used as aknob for controlling a volume up-or-down by the user, if a program of amusic play is installed in the smart watch.

FIG. 5B is the side view illustrating the second configuration exampleof the sensing unit of the electronic apparatus in accordance with thefirst embodiment of the disclosure.

Similar to the first configuration example, in the second configurationexample, the first visible portion 1041 and the sense region are on thesame lateral surface with a first angle with respect to the externalsurface of the annular or the approximated annular space concurrently,and the display direction of the first visible portion 1041 is in adirection with the first angle with respect to the outward direction ofthe annular or the approximated annular space, as well as the firstvisible portion 1041 is nested inside at least part of the frame formedby the sense region.

In a simple case, the first angle is 90 degrees when the cross sectionof the body device 101 is a square. At this point, the first visibleportion 1041 and the sense region are on the same lateral surfaceperpendicular to the external surface of the annular or the approximatedannular space concurrently, and the display direction of the firstvisible portion 1041 is in a direction perpendicular to the outwarddirection of the annular or the approximated annular space, as well asthe first visible portion 1041 is nested inside at least part of a frameformed by the sense region.

For example, the display surface of the near-to-eye display and thetouch surface of the touch screen are both on a lateral region, i.e., alateral surface of the surface portion, e.g., a plane where a wind-upknob in the common watch is located or a plane connected with the strapportion, of the dial portion of the smart watch, and a frame of thedisplay surface is formed by the touch surface, so as to enclose theperiphery of the display surface entirely, as shown in FIG. 5B. However,it is appreciated readily by those skilled in the art that thedisclosure is not limited thereto. For example, the display surface andthe touch surface may also be both on the strap portion of the smartwatch. Further, a portion in the frame of the display surface may alsobe formed by the touch surface, so as to enclose the periphery of thedisplay surface partially.

Alternatively, the first angle may be other angles, such as 30 or 60degrees, when the cross section of the body device 101 is a polygon.

In the second situation, the first display unit 104 and the sensing unit106 are set concurrently on the holding device, e.g., the strap portionof the smart watch, or the first display unit 104 and the sensing unit106 are set concurrently on the body device 101, e.g., the dial portionof the smart watch, as well as the first region and the sensing unit areon two planes with the first angle. In a simple case, the first regionand the sense region are on two surfaces perpendicular to each otherwhen the cross section of the body device 101 is a square, as describedabove. That is, the sense region, e.g., the touch surface, and the firstvisible portion 1041, e.g., the display surface of the near-to-eyedisplay, may be set on two different planes perpendicular to each other.However, it is appreciated readily by those skilled in the art that thedisclosure is not limited thereto. For example, the first region and thesense region may also be on two adjacent planes with some angle therebetween.

The different configuration examples of the first display unit and thesensing unit in the second situation will be depicted with reference toFIGS. 5C and 5D hereinafter.

FIG. 5C is the side view illustrating the third configuration example ofthe sensing unit of the electronic apparatus in accordance with thefirst embodiment of the disclosure.

In the third configuration example, the first visible portion 1041 is onthe external surface of the annular or the approximated annular space,and the display direction of the first visible portion 1041 is in theoutward direction of the annular or the approximated annular space, aswell as the sense region is on a lateral surface perpendicular, or morecommonly, with the first angle, to the external surface of the annularor the approximated annular space. For example, the display surface ofthe near-to-eye display is on the frontal region of the dial portion,i.e., the top surface of the dial portion, of the smart watch, and thetouch surface of the touch screen is on the lateral region of the dialportion, i.e., the lateral surface of the surface portion, e.g., theplane where the wind-up knob in the common watch is located or the planeconnected with the strap portion, of the smart watch, as shown in FIG.5C.

It is noted that, when the expression “two planes are perpendicular toeach other” is present hereinafter, more generally, the two planes mayhave other first angles in addition to the 90 degrees there between aswell.

FIG. 5D is the side view illustrating the fourth configuration exampleof the sensing unit of the electronic apparatus in accordance with thefirst embodiment of the disclosure.

In the fourth configuration example, the first visible portion 1041 ison a lateral surface perpendicular to the external surface of theannular or the approximated annular space, and the display direction ofthe first visible portion 1041 is in a direction perpendicular to theoutward direction of the annular or the approximated annular space, aswell as the sense region is on the external surface of the annular orthe approximated annular space. For example, the display surface of thenear-to-eye display is on the lateral region of the dial portion, i.e.,the lateral surface of the surface portion, e.g., the plane where thewind-up knob in the common watch is located or the plane connected withthe strap portion, of the smart watch, and the touch surface of thetouch screen is on the front surface region of the dial portion, i.e.,the top surface of the dial portion, of the smart watch, as shown inFIG. 5D.

However, it is appreciated readily by those skilled in the art that thedisclosure is not limited thereto. For example, it is possible that thefirst visible portion 1041 is on the first lateral surface with thefirst angle with respect to the external surface of the annular or theapproximated annular space, and the display direction of the firstvisible portion 1041 is in a direction with the first angle with respectto the outward direction of the annular or the approximated annularspace, as well as the sense region is on a second lateral surface with asecond angle with respect to the external surface of the annular or theapproximated annular space, and the second and first lateral surfacesare two lateral surfaces with a third angle there between. Apparently,any two among the first, second, and third angles may be identical ordifferent.

In a simple case, that is, in the case where it is assumed that all ofthe first, second, and third angles are 90 degrees, the first visibleportion 1041 is on the first lateral surface perpendicular to theexternal surface of the annular or the approximated annular space, andthe display direction of the first visible portion 1041 is in thedirection perpendicular to the outward direction of the annular or theapproximated annular space, as well as the sense region is on the secondlateral surface perpendicular to the external surface of the annular orthe approximated annular space, and the second and first lateralsurfaces are two lateral surfaces perpendicular to each other. Forexample, the display surface of the near-to-eye display is on thelateral region of the dial portion, i.e., the first lateral surface ofthe surface portion, e.g., the plane where the wind-up knob in thecommon watch is located, of the smart watch, and the touch surface ofthe touch screen is on the lateral region of the dial portion, i.e., asecond lateral surface perpendicular to the first lateral surface of thesurface portion, e.g., the plane connected with the strap portion in thecommon watch, of the smart watch.

Despite an illustration of different position relationships between thefirst display unit and the sensing unit in the second situation throughthe third to fourth configuration examples hereinabove. However, it isappreciated readily by those skilled in the art that the disclosure isnot limited thereto. For example, the touch surface may not form theframe of the display surface, or may also form the entire or part of theframe of the display surface, so as to enclose the periphery of thedisplay surface entirely or partially. The display surface and the touchsurface may also be both on the strap portion of the smart watch.

Moreover, in the latter case, the first region and the sense region maybe non-adjacent regions between which there is not a common side. Thatis, the relative position relationship between a display surface, i.e.,the first region where the first visible portion 1041 is located, of thefirst display unit 104, e.g., which may be one near-to-eye display, andthe sense region, e.g., a touch surface, of the sensing unit 106, e.g.,the touch screen, is non-adjacent. More particularly, the latter casemay also include two different situations as follows.

In a third situation, one of the first display unit 104 and the sensingunit 106 is set on the body device 101, e.g., the dial portion of thesmart watch, and the other of the first display unit 104 and the sensingunit 106 is set on the holding device, e.g., the strap portion of thesmart watch.

The different configuration examples of the first display unit and thesensing unit in the third situation will be depicted with reference toFIGS. 5E and 5F hereinafter.

FIG. 5E is the side view illustrating the fifth configuration example ofthe sensing unit of the electronic apparatus in accordance with thefirst embodiment of the disclosure.

In the fifth configuration example, the first visible portion 1041 andthe sense region are on the external surface of the annular or theapproximated annular space concurrently, and the display direction ofthe first visible portion 1041 is in the outward direction of theannular or the approximated annular space. For example, the displaysurface of the near-to-eye display is on the lateral region of the dialportion, i.e., the lateral surface of the surface portion, e.g., theplane where the wind-up knob in the common watch is located or the planeconnected with the strap portion, of the smart watch, and the touchsurface of the touch screen is on the frontal region of the dialportion, i.e., the external surface of the dial region, of the smartwatch, as shown in FIG. 5E.

That is, the touch screen is set on the strap portion of the smartwatch, and the near-to-eye display system is set on the dial portion ofthe smart watch, as well as the output window is in the lateraldirection of the watch, at this point, it is concerned that the touchscreen may be used as an absolute or relative position controlapparatus.

FIG. 5F is the side view illustrating the sixth configuration example ofthe sensing unit of the electronic apparatus in accordance with thefirst embodiment of the disclosure.

In the sixth configuration example, the direction of an outer normalline of the sense region and the image output direction of the firstvisible portion are opposite radially to each other in the annular orthe approximated annular space. For example, the display surface of thenear-to-eye display is on the lateral region of the dial portion, i.e.,the lateral surface of the surface portion, e.g., the plane where thewind-up knob in the common watch is located or the plane connected withthe strap portion, of the smart watch, and the touch surface of thetouch screen is on the strap portion of the smart watch and distantfarthest from the dial portion, making both of them on the oppositepositions at a ring formed at the smart watch, as shown in FIG. 5F.

However, it is appreciated readily by those skilled in the art that thedisclosure is not limited thereto. For example, the display surface ofthe near-to-eye display may also be on the front surface region of thedial portion, i.e., the top surface of the dial portion, of the smartwatch, and the touch surface of the touch screen is on the front surfaceregion of the strap portion, i.e., the external surface of the strapportion, of the smart watch, as well as both of them are arranged on twoopposite positions across a radial direction of the holding device 102,that is, on the two ends distant farthest from each other on the annularformed by the smart watch. As such, an interactive operation may beperformed conveniently on the sensing unit 106, when a graphic interfaceis viewed through the first display unit 104 by the user, and the useris enabled to know the extent and position of the touch operationconveniently according to feedback of the same direction or even thesame extent of the displayed content for the touch operation, since thedisplay direction of the first display unit 104 is just opposite to thetouch input direction of the sensing unit 106.

In the fourth situation, the first display unit 104 and the sensing unit106 are set concurrently on the holding device, e.g., the strap portionof the smart watch, or the first display unit and the sensing unit areset concurrently on the body device 101, e.g., the dial portion of thesmart watch, as well as the first region and the sense region are on twoopposite planes. For example, those two planes may be two completely orapproximately parallel planes. That is, the sense region, e.g., thetouch surface, and the first visible portion 1041, e.g., the displaysurface of the near-to-eye display, may be set on two different planesparallel completely or approximately with each other. However, it isappreciated readily by those skilled in the art that the disclosure isnot limited thereto. For example, the first region and the sense regionmay also be on two adjacent planes with some angle there between.

The different configuration examples of the first display unit and thesensing unit in the fourth situation will be depicted with reference toFIG. 5G hereinafter.

FIG. 5G is the side view illustrating the seventh configuration exampleof the sensing unit of the electronic apparatus in accordance with thefirst embodiment of the disclosure.

In the seventh configuration example, the first visible portion 1041 ison the external surface of the annular or the approximated annularspace, and the display direction of the first visible portion 1041 is inthe outward direction of the annular or the approximated annular space,as well as the sense region is on the internal surface of the annular orthe approximated annular space. For example, the display surface of thenear-to-eye display is on the front surface region of the dial portion,i.e., the top surface of the dial portion, of the smart watch, and thetouch surface of the touch screen is on the back surface of the dialportion, i.e., the bottom surface of the dial portion, of the smartwatch, as shown in FIG. 5G. As such, the display output and the touchinput will not interfere with each other when the smart watch is held onthe hand for use by the user, and the touch region of the touch screenis maximum, which enables the user to use the absolute position controlcorresponding one-to-one to both of the touch and display positions,such that a convenient input way is provided for the user, although suchstructure will cause the touch surface of the touch screen to be blockedby the wrist of the user when the smart watch is wore on the wrist.

An interactive operation may be performed conveniently on the sensingunit 106, when the graphic interface is viewed through the first displayunit 104 by the user, and the user is enabled to know the extent andposition of the touch operation conveniently according to feedback ofthe same direction or even the same extent of the displayed content forthe touch operation, since the display direction of the first displayunit 104 is just opposite to the touch input direction of the sensingunit 106, such that a user experience for the absolute or relativeposition control penetrating the electronic apparatus is provided forthe user, extending the existing operation way.

However, it is appreciated readily by those skilled in the art that thedisclosure is not limited thereto. For example, it is possible that thefirst visible portion 1041 is on the first lateral surface with thefirst angle with respect to the external surface of the annular or theapproximated annular space, and the display direction of the firstvisible portion 1041 is in the direction with the first angle withrespect to the outward direction of the annular or the approximatedannular space, as well as the sense region is on the second lateralsurface with a second angle with respect to the external surface of theannular or the approximated annular space, and the second and firstlateral surfaces are two lateral surfaces opposite to each other.Apparently, the first and second angles may be identical or different.

In a simple case, that is, in the case where it is assumed that all ofthe first and second angles are 90 degrees, the first visible portion1041 is on the first lateral surface perpendicular to the externalsurface of the annular or the approximated annular space, and thedisplay direction of the first visible portion 1041 is in the directionperpendicular to the outward direction of the annular or theapproximated annular space, as well as the sense region is on the secondlateral surface perpendicular to the external surface of the annular orthe approximated annular space, and the second and first lateralsurfaces are two lateral surfaces opposite to each other. For example,the two lateral surfaces may be completely or approximately parallel,that is, the angle there between is less than a predetermined angle,e.g., 30 degrees.

Second Embodiment

In the second embodiment, the acquisition unit 106 may comprise an imagecapture unit for capturing an image so as to generate a first imagecapture signal.

For example, the acquisition unit 106 may be an image capture unit,e.g., a camera or an array of cameras, for capturing an image or videosignal. In the electronic apparatus 100, such image capture unit may beused to take photos or videos simply, and to store them in theelectronic apparatus 100 or to display them to the user through thefirst display unit 104.

The image capture unit may also be used to capture an action controloperation generated by the operating object so as to generate the firstimage capture signal, and the processing unit 103 generates a firstcontrol signal according to the first image capture signal and controlsthe electronic apparatus 100 to perform the first control signal.

For example, the acquisition unit 106 may be the image capture unit,e.g., a camera, for capturing an interactive action of the operatingobject, e.g., an iris, a finger, a palm, a body action, a user gesture,and so on, in an image capture space. In the electronic apparatus 100,the image capture unit may be used to take a modality, a gesture action,or a body action of the user, such that the electronic apparatus iscontrolled by the processing unit 103 according to those actions tocomplete various operations.

A relative position relationship between the image capture unit 106 andthe first display unit 104 and/or other units in the electronicapparatus 100 may be configured optimally, in order to ensure that theuser is able to take images and/or input the interactive controloperation to the electronic apparatus 100 more conveniently and flexiblyby using the image capture unit 106 while viewing a response to suchinteractive control operation of the image capture unit and/or theelectronic apparatus 100 by using the first display unit 104.

For example, for the near-to-eye optical display system, a sensing unit,e.g., a camera or other sensor, may be set at an appropriate position ina housing unit (the body unit) of the apparatus to recognize a motion ofthe hands for the interactive control.

The first display unit 104 comprises a first visible portion 1041 whichis a portion viewed by the user so as to perceive or see a displayedcontent thereof in the first display unit and located on a first region,as described above. The image capture unit 106 has one image capturedirection in which the action control operation generated by theoperating object is captured by the image capture unit 106.

Particularly, in the first case, the image capture unit 106 may be theacquisition unit for capturing the actions of the irises and eyeballs ofthe user. That is, a vision positioning monitor unit may be integratedin the near-to-eye optical display system, such that a detection byfingerprint is replaced with a detection by iris to conduct an identityrecognition and/or the touch input is replaced with a vision control tocontrol the electronic apparatus to perform various operations. Suchacquisition unit may acquire the action of the irises and eyeballs ofthe user synchronously while the displayed content is viewed through thefirst display unit 104, e.g., the near-to-eye display, by the user, inorder to achieve the operations of authentication, vision control, andthe like, such that the control action and the viewing action of theuser are integrated together, simplifying the operations of the user.However, the present disclosure is not limited thereto. The acquisitionoperation of the acquisition unit may also be conducted individuallyindependent of the display operation of the first display unit.

Thus, the first display unit 104 and the image capture unit 106 are seton the holding device 102, e.g., the strap portion of the smart watch,concurrently, or the first display unit 104 and the image capture unit106 are set on the body device 101, e.g., the dial portion of the smartwatch, concurrently, and the image capture direction of the imagecapture unit 106 is the same as the image output direction of the firstvisible portion 1041 of the first display unit 104. That is, when aniris detection or operation control is conducted by the image captureunit 106, e.g., an iris camera, the first display unit, e.g., thenear-to-eye display, and the iris camera have to be on the dial or strapportions of the smart watch concurrently, and the image displaydirection and the image acquisition direction should be in an overlappedor approximately overlapped position relationship.

In the first situation, the first visible portion 1041 is on the surfaceof the annular or the approximated annular space, and the image captureunit 106 is inside the annular or the approximated annular space, thetransmittance rate of the first visible portion 1041 is compliant with apredetermined condition in a direction opposite to the displaydirection, enabling the image capture unit 106 to capture the imagethrough the first visible portion 1041. That is, the near-to-eye displayis on the surface (the external or internal surface) of the dial orstrap portion of the smart watch and is transparent, and the iris camerais set inside the near-to-eye display perpendicular to or parallel withit.

The different configuration examples of the first display unit and theimage capture unit in the first situation will be depicted withreference to FIGS. 7A and 7B hereinafter.

FIG. 7A is the side view illustrating the first configuration example ofan image capture unit of the electronic apparatus in accordance with asecond embodiment of the disclosure.

In the first configuration example, the image capture unit and the firstvisible portion have a fourth angle there between and are at leastpartly set to be overlapped, enabling the external light to be incidentinto the image capture unit across the first visible portion. Forexample, the fourth angle may have an angle less than 30 degrees. Thefourth angle may be 0 degree, that is, the image capture unit and thefirst visible portion are set to be parallel and at least partlyoverlapped with each other. Thus, a refraction generated when theexternal light transmits through the first visible portion may belowered to the minimum, causing more light to be incident into the imagecapture unit.

In one implementation of the first configuration example, the firstvisible portion 1041 is on the external surface of the annular or theapproximated annular space, and the display direction of the firstvisible portion 1041 is in the outward direction of the annular or theapproximated annular space, and the image capture unit 106 and the firstvisible portion 1041 are set to be parallel, or more generally, with thefourth angle, the same below, and at least partly overlapped with eachother, enabling the external light to transmit through the first visibleportion so as to be incident into the image capture unit 106. Thenear-to-eye display is set on the external surface of the dial or strapportion of the watch, and the transmittance rate is compliant with thepredetermined condition in the outward direction of the annular or theapproximated annular space, as shown in FIG. 7A. The predeterminedcondition may be that the transmittance rate is greater than or equal toa predetermined value, such as 70%. The iris camera is set inside thenear-to-eye display parallel therewith, and overlapped with a projectionof the near-to-eye display completely or partially. Thus, the firstdisplay unit 1041 may be enabled not to interfere with the image capturefunction of the iris camera, such that a more compact configuration isachieved.

It is to be noted that when the expression “the image capture unit 106is parallel with the first visible portion 1041” is present hereinafter,more generally, the two apparatuses may have other fourth angles ratherthan 0 degree there between as well.

However, it is appreciated readily by those skilled in the art that thedisclosure is not limited thereto. For example, it is possible inanother implementation that the first visible portion 1041 is on thelateral surface perpendicular to, or more generally, with the firstangle with respect to, the external surface of the annular or theapproximated annular space, and the display direction of the firstvisible portion 1041 is in the direction perpendicular to, or moregenerally, with the first angle with respect to, the outward directionof the annular or the approximated annular space, as well as the imagecapture unit is set to be parallel with, or more generally, with thefourth angle with respect to, or at least part overlapped with the firstvisible portion 1041, enabling the external light to transmit throughthe first visible portion 1041 to be incident into the image captureunit. That is, the near-to-eye display may also be set on the lateralsurface of the dial or strap portion of the watch, and the transmittancerate is compliant with the predetermined condition in the directionperpendicular to the outward direction of the annular or theapproximated annular space, as shown in FIG. 7A. The iris camera is setinside the near-to-eye display parallel therewith, and overlapped withthe projection of the near-to-eye display completely or partially.

FIG. 7B is the side view illustrating the second configuration exampleof the image capture unit of the electronic apparatus in accordance withthe second embodiment of the disclosure.

In the second configuration example, the image capture unit and thefirst visible portion are set with a fifth angle there between and notoverlapped with each other, enabling the external light to transmitthrough the first visible portion so as to be incident into the annularor the approximated annular space, and then into the image capture unitvia one reflective mirror. For example, the fifth angle may have anyangle. The fifth angle may be 90 degrees, that is, the image captureunit is set to be perpendicular to the first visible portion. In thatcase, the reflective mirror may be set obliquely by an angle of 45degrees with respect to the first visible portion and the image captureunit. However, the present disclosure is not limited thereto. The imagecapture unit, the first visible portion, and the reflective mirror maybe set with any angle there among, as long as the external lighttransmitted through the first visible portion may be incident into theimage capture unit by the reflective mirror.

It is stated that the reflective mirror is required to have necessarilya transmission function in a particular direction in addition to thereflective function, that is, the reflective mirror is a type ofhalf-transmission and half-reflection lens, enabling the lightcorresponding to the first image, emitted from the first displaycomponent 301 to be delivered to the first optical component 302 whilethe external light transmitted through the first visible portion isincident into the image capture unit, such that the first opticalcomponent 302 conduct a light path conversion on the light correspondingto the first image to form an enlarged virtual image corresponding tothe first image for viewing through the first visible portion 1041 bythe user.

To this end, the reflective mirror may be a half-transparent glass lensof which the transmittance rate is greater than a predetermined value,such as 70%, in a first direction, and less than or equal to apredetermined value, such as 30%, in a second direction. Alternatively,the reflective mirror may also be the following optical componentshaving two states of ON and OFF and switching between the two statesquickly to transmit or reflect the external light in time division. Thatis, the light corresponding to the first image, emitted from the firstdisplay component 301 is capable of being sent to the first opticalcomponent 302 by the reflective mirror in the ON state, and the externallight incident through the first visible portion 1041 is capable ofbeing sent to the image capture unit 106 by the reflective mirror in theOFF state.

In one implementation of the second configuration example, the firstvisible portion 1041 is on the external surface of the annular or theapproximated annular space, and the display direction of the firstvisible portion 1041 is in the outward direction of the annular or theapproximated annular space, as well as the image capture unit 106 is setto be perpendicular to, or more generally, with the fifth angle withrespect to, the same below, the first visible portion 1041, enabling theexternal light to transmit through the first visible portion 1041 so asto be incident into the annular or the approximated annular space, andthen incident into the image capture unit 106 via one reflective mirrorset obliquely by an angle of 45 degrees with respect to the firstvisible portion 1041 and the image capture unit 106. The near-to-eyedisplay is set on the external surface of the dial or strap portion ofthe watch, and the transmittance rate is compliant with thepredetermined condition in the outward direction of the annular or theapproximated annular space, as shown in FIG. 7B. The predeterminedcondition may be that the transmittance rate is greater than or equal toa predetermined value, such as 70%. This iris camera is set inside thenear-to-eye display, through which the external light is transmitted isreceived by the 45-degree reflective mirror, perpendicular therewith. Tothis end, a probe light source, e.g., an infrared, may be built in theiris camera and incident into the eyes of human via the 45-degreereflective mirror, and the movement of the eyeballs will transfer intothe iris camera via a reverse path.

However, it is appreciated readily by those skilled in the art that thedisclosure is not limited thereto. For example, it is possible inanother implementation that the first visible portion 1041 is on thelateral surface perpendicular to, or more generally, with the firstangle with respect to, the external surface of the annular or theapproximated annular space, and the display direction of the firstvisible portion 1041 is in the direction perpendicular to, or moregenerally, with the first angle with respect to, the outward directionof the annular or the approximated annular space, as well as the imagecapture unit is set to be perpendicular to, or more generally, with thefifth angle with respect to, the first visible portion 1041, enablingthe external light to transmit through the first visible portion 1041 tobe incident into the annular or the approximated annular space, and thenincident into the image capture unit via one reflective mirror setobliquely by 45 degrees with respect to the first visible portion 1041and the image capture unit.

In the second situation, the first visible portion 1041 and the imagecapture unit 106 are on the surface of the annular or the approximatedannular space concurrently, and the image capture unit 106 is set on atleast part of the region around which the first visible portion isenclosed. That is, the near-to-eye display and the iris camera are onthe surface (the external or lateral surface) of the dial or strapportion of the smart watch concurrently, and the iris camera constitutesthe entire or part of the frame of the near-to-eye display.

The different configuration examples of the first display unit and theimage capture unit in the second situation will be depicted withreference to FIGS. 7C and 7D hereinafter.

FIG. 7C is the top view illustrating the third configuration example ofthe image capture unit of the electronic apparatus in accordance withthe second embodiment of the disclosure.

In the third configuration example, the first visible portion 1041 andthe image capture unit 106 are on the external surface of the annular orthe approximated annular space concurrently, and the display directionof the first visible portion 1041 is in the outward direction of theannular or the approximated annular space, and the first visible portion1041 is nested inside at least part of the frame formed by the imagecapture unit 106. For example, the first visible portion 1041 of thenear-to-eye display and the group of lenses of the camera are both onthe frontal region of the dial portion, i.e., the top surface of thedial portion, of the smart watch, and the frame of the first visibleportion 1041 is formed by the group of lenses, in order to enclosecompletely the periphery of the first visible portion 1041, as shown inFIG. 7C. However, it is appreciated readily by those skilled in the artthat the disclosure is not limited thereto. For example, the near-to-eyedisplay and the video camera may also be both on the strap portion ofthe smart watch. Further, a portion in the frame of the near-to-eyedisplay may also be formed by the camera, so as to partially enclose theperiphery of the near-to-eye display.

FIG. 7D is the side view illustrating the fourth configuration exampleof the image capture unit of the electronic apparatus in accordance withthe second embodiment of the disclosure.

Similar to the third configuration example, in the fourth configurationexample, the first visible portion 1041 and the image capture unit 106are on the same lateral surface perpendicular to the external surface ofthe annular or the approximated annular space concurrently, and thedisplay direction of the first visible portion 1041 is in the directionperpendicular to the outward direction of the annular or theapproximated annular space, as well as the first visible portion 1041 isnested inside at least part of the frame formed by the image captureunit 106. However, it is appreciated readily by those skilled in the artthat the disclosure is not limited thereto. For example, the near-to-eyedisplay and the camera may also be both on the strap portion of thesmart watch. Further, a portion in the frame of the near-to-eye displaymay also be formed by the camera, so as to enclose the periphery of thenear-to-eye display partially.

In addition, particularly, in the second situation, the image captureunit 106 may be other image capture units, e.g., a common camera, ratherthan the iris camera, for a simple capture and storage of the image or acapture of the interactive actions in the image capture space by otheroperating objects, e.g., a finger, a palm, a body action, a usergesture, and so on.

To this end, the image capture direction of the image capture unit 106is different from the image output direction of the first visibleportion 1041 of the first display unit 104. That is, the image displaydirection and the image acquisition direction should be in anon-overlapped position relationship.

In the third situation, the first display unit 104 and the image captureunit 106 are set on the holding device 102, e.g., the strap portion ofthe smart watch, concurrently; or one of the first display unit and theimage capture unit is set on the body device 101, e.g., the dial portionof the smart watch, and the other of the first display unit and theimage capture unit is set on the holding device 102, e.g., the strapportion of the smart watch.

The different configuration examples of the first display unit and theimage capture unit in the third situation will be depicted withreference to FIGS. 7E and 7F hereinafter.

FIG. 7E is the side view illustrating the fifth configuration example ofthe image capture unit of the electronic apparatus in accordance withthe second embodiment of the disclosure.

In the fifth configuration example, the image capture direction of theimage capture unit 106 and the image output direction of the firstvisible portion 1041 are opposite radially to each other in the annularor the approximated annular space. For example, the near-to-eye displaymay be on the frontal region of the dial portion, i.e., the top surfaceof the dial portion, of the smart watch, and the group of lenses of thecommon camera is on the frontal region of the strap portion, i.e., theexternal surface of the strap portion, of the smart watch, and both ofthem are arranged at two opposite positions across the radial directionof the holding device 102, as shown in FIG. 7E. Similarly, thenear-to-eye display may be on the frontal region of the strap portion,i.e., the external surface of the strap portion, of the smart watch, andthe group of lenses of the common camera may also be on the frontalregion of the strap portion, i.e., the external surface of the strapportion, of the smart watch, as well as both of them are arranged at twoopposite positions across the radial direction of the holding device102. In other words, one of the near-to-eye display and the commoncamera is on the dial portion of the smart watch, and the other is onthe strap portion of the smart watch, or the near-to-eye display and thecommon camera are on the strap portion of the smart watch concurrently,and the near-to-eye display and the common camera are in a face-to-faceposition relationship on the annular formed by the watch. As such, whena live image captured by the image capture unit 106 is displayed on thefirst visible portion 1041, the user is enabled to view the image astransmitted through the electronic apparatus 200 by the first visibleportion 1041, since the capture direction of the sensor unit 106 iscoincident with the view direction of the eyes of the user.

It is stated that a processing unit 103, a second display unit 105, asensing unit 106, and a battery unit 107, etc. may in practice beomitted in the present configuration example, despite those units arealso illustrated in FIG. 7E.

FIG. 7F is the side view illustrating the sixth configuration example ofthe image capture unit of the electronic apparatus in accordance withthe second embodiment of the disclosure.

In the sixth configuration example, the image capture direction of theimage capture unit and the image output direction of the first visibleportion 1041 are perpendicular to each other radially in the annular orthe approximated annular space. For example, the near-to-eye display maybe on the frontal region of the dial portion, i.e., the top surface ofthe dial portion, of the smart watch, and the group of lenses of thecommon camera is on the frontal region of the strap portion, i.e., theexternal surface of the strap portion, of the smart watch, as well asboth of them are arranged at two opposite positions perpendicular toeach other in the radial direction of the holding device 102, as shownin FIG. 7F. Similarly, the near-to-eye display may be on the frontalregion of the strap portion, i.e., the external surface of the strapportion, of the smart watch, and the group of lenses of the commoncamera may also be on the frontal region of the strap portion, i.e., theexternal surface of the strap portion, of the smart watch, as well asboth of them are arranged at two opposite positions perpendicular toeach other in the radial direction of the holding device 102. In otherwords, one of the near-to-eye display and the common camera is on thedial portion of the smart watch, and the other is on the strap portionof the smart watch, or the near-to-eye display and the common camera areon the strap portion of the smart watch concurrently, and thenear-to-eye display and the common camera are in a perpendicularposition relationship on the annular formed by the watch. Such positionrelationship makes the view direction in which the first display unit isviewed by the user be different from the photograph direction in which aview is found by the video camera, such that a user experience similarto a periscope is formed, by which it is convenient for the user toperform photographing process secretly.

It is stated that the processing unit 103, the second display unit 105,the sensing unit 106, and the battery unit 107, etc. may in practice beomitted in the present configuration example, despite those units arealso illustrated in FIG. 7F. In addition, FIG. 7F further illustratesthat the common camera may be at other positions, for example, theposition at which the image capture units 1061 (in fact, equivalent tothe fifth configuration example), 1062, and 1063 is located, rather thanthose described above, and other positions (not shown).

That is, various cameras for different usages may be set in respectivedirections in the housing unit, and may also be set respectivedirections in the holding unit, such that it is convenient for theacquisition, interactive control, and Augmented Reality (AR) for thevideo and image. For example, the image may be captured and analyzed bythe image capture unit 106, such that a recognition result obtained byanalysis is displayed individually through the first visible portion1041 or displayed with the picture displayed at the first visibleportion 1041 overlapped.

In an application of Augmented Reality, the image from the natural worldmay be overlapped with that from the near-to-eye optical display system.For example, the real world is viewed by one eye of the user, and theauxiliary information is obtained through the near-to-eye opticaldisplay system by the other eye. In addition, the video and image fromthe real world may be acquired by the camera, input to the near-to-eyeoptical display system, and overlapped with the information which wouldhave been displayed by the near-to-eye optical display system.

In the fourth situation, the first display unit 104 and the imagecapture unit 106 are set concurrently on the body device 101, e.g., thedial portion of the smart watch.

The different configuration examples of the first display unit and theimage capture unit in the fourth situation will be depicted withreference to FIG. 7G hereinafter.

FIG. 7G is the side view illustrating the seventh configuration exampleof the image capture unit of the electronic apparatus in accordance withthe second embodiment of the disclosure.

In the seventh configuration example, the first visible portion 1041 ison the first lateral surface perpendicular to the external surface ofthe annular or the approximated annular space, and the display directionof the first visible portion 1041 is in the direction perpendicular tooutward direction of the annular or the approximated annular space, aswell as the image capture unit 106 is on the second lateral surfaceperpendicular to the external surface of the annular or the approximatedannular space, and the second and first lateral surfaces are twoopposite lateral surfaces, the image capture direction of the imagecapture unit 106 is opposite to the display direction of the firstvisible portion 1041. For example, the near-to-eye display and thecommon camera are on the dial portion of the smart watch concurrently,and near-to-eye display and the common camera are in a face-to-faceposition relationship on the dial portion, as shown in FIG. 7G.

As such, when a live image captured by the image capture unit 106 isdisplayed on the first display unit 104, the user is enabled to view theimage as transmitted through the electronic apparatus 100 by the firstdisplay unit 104, since the capture direction of the image capture unit106 is coincident with the view direction of the eyes of the user.

However, it is appreciated readily by those skilled in the art that thedisclosure is not limited thereto. For example, the first visibleportion 1041 is on the external surface of the annular or theapproximated annular space, and the display direction of the firstvisible portion 1041 is in the outward direction of the annular or theapproximated annular space, as well as the image capture unit 106 is onthe internal surface of annular or the approximated annular space, andthe image capture direction of the image capture unit 106 is opposite tothe display direction of the first visible portion 1041. That is, thenear-to-eye display is on the external surface of the dial portion ofthe smart watch, and the common camera is on the internal surface of thedial portion of the smart watch. As such, the photograph habit of theuser is satisfied most when the smart watch is held on the hand by theuser, such that it is provided a convenient photographing way for theuser, although such structure makes the group of lenses of the commoncamera to be blocked by the wrist of the user when the smart watch isworn on the wrist.

To this end, in the case where one closed annular-like space is formedby the holding device 102 in a holding state, the holding device 102further comprises one open state. Thus, the holding device 102 isswitched from the holding state to the open state for a completion ofthe photograph operation by the user, which avoids a view findingposition for the image capture unit 106 from being blocked.Alternatively, in the case where one non-closed approximated annularspace is formed by the holding device 102 in the holding state, theholding device 102 may also comprise one open state, or may set theholding device 102 to make the opening portion adjacent to theapproximated annular space to be aligned with the image capturedirection of the image capture unit 106, and set the size of the openingportion so that the view finding position of the image capture unit 106at least cannot be blocked, that is, make the holding device 102 not tobe present within an imaging range of the image capture unit 106.

Third Embodiment

In the third embodiment, the acquisition unit 106 may comprise a soundcapture unit for capturing a sound so as to generate a first soundcapture signal.

For example, the acquisition unit 106 may be a sound capture unit forcapturing an audio signal, e.g., a microphone or an array ofmicrophones. In the electronic apparatus 100, the sound capture unit maybe used to record the audios simply, and store them in the electronicapparatus 100 or play them to the user through a sound play unit, suchas a speaker.

The sound capture unit may also be used to capture a sound controloperation generated by the user so as to generate the first soundcapture signal, and the processing unit 103 generates a first controlsignal according to the first sound capture signal and controls theelectronic apparatus 100 to perform the first control signal.

For example, the acquisition unit 106 may be the sound capture unit,e.g., a microphone, for capturing and recognizing a voice command of theuser. In the electronic apparatus 100, the electronic apparatus iscontrolled by the processing unit 103 to complete various operationsaccording to those voice commands.

In order to ensure the user is able to record the sound efficiently byusing the sound capture unit 106 for a purpose of sound record, etc.,the relative position relationship between the sound capture unit 106and the image capture unit and/or other units in the electronicapparatus 100 may be configured optimally.

Particularly, in the first case, the electronic apparatus 100 may alsocomprise an image capture unit for capturing the image to generate thefirst image capture signal, as described above. The sound capture unit106 and the image capture unit are set concurrently at the adjacentpositions on the holding device 102, or the sound capture unit and theimage capture unit are set concurrently at the adjacent positions on thebody device 101. That is, the microphone and the camera are setadjacently, such that a sound signal related to the video taken by thecamera is acquired by the microphone.

For example, in the case where the smart watch comprises a plurality ofcameras and a plurality of microphones, when a certain camera therein isrecording video, one or more microphones adjacent to the camera andoriented identically may be enabled, and the other microphones are turnoff, to achieve an directional acquisition.

Particular, in the second case, the sound capture unit 106 may be a setof acquisition units arranged at respective positions of the electronicapparatus 100 and used to capture the voice of the user or the soundfrom other sound source in different angles.

To this end, the sound capture unit 106 is an array of sound captureunits comprising a plurality of sound capture subunits, each soundcapture subunit in the array of sound capture units is set spaced on atleast one of the body device and the holding device, and each soundcapture subunit is made to capture the sound so as to generate the firstsound capture signal when the sound is made by the user, and theprocessing unit 103 compares the intensities of the first sound capturesignals generated by each sound capture subunit, and turns off othersound capture subunits other than those by which the first sound capturesignals generated have the maximum intensities. That is, each microphonein the array of microphones can be controlled to be switched accordingto the sound intensity.

However, it is appreciated readily by those skilled in the art that thedisclosure is not limited thereto. Particularly, the array ofmicrophones can be switched in other manners. For example, one or moremicrophones in a work state may be controlled automatically depending onspecific application. For example, when the camera is used to takevideo, one or more microphones at the same side may be turned on, so asto obtain a best audio stream. Alternatively, when the smart watch isused for a voice event record by the user, one or more microphonesnearest to the mouth of the user may be turned on, or one or moremicrophones convenient most for a sound record operation, e.g., one ormore microphones on the dial of the watch, may be turned on.Alternatively, apparently, the array of microphones may be turned on andoff selectively through a manual control by the user.

Further, in addition to working selectively, all microphones in thearray of microphones may also work concurrently, such that the concernedsound and the ambient noise are recorded in different angles, and theinterference is shielded subsequently by the operations of comparison,recognition, filteannular, and the like, in order to achieve thedirectional acquisition. For example, when three persons are speaking infront of the electronic apparatus at present, the electronic apparatusmay be made to retain the sound of one or two of those persons andeliminate the sound of others by recognizing and filteannular the soundof the three persons, so as to satisfy the special requirement of theuser.

Fourth Embodiment

In the fourth embodiment of the disclosure, the acquisition unit 106 maycomprise a biometric capture unit for capturing a first biometricinformation of the user.

For example, the acquisition unit 106 may be a biometric sensor forcapturing the biometric feature. More particularly, the biometricfeature may be divided into an external biometric feature comprising afingerprint, a palm print, an iris, a voice print, and the like, and aninternal biometric feature comprising an electromyography, a bodytemperature, a cardiac rate, a blood glucose content, a vena state, anda calorie consumption, etc. Accordingly, in the case of the externalbiometric feature, the biometric sensor may be a touch screen forcapturing the fingerprint and/or the palm print, and may also be acamera for capturing the fingerprint, the palm print, and/or the iris,and may also be a microphone for capturing the sound print, and may alsobe an electromyography sensor for capturing the electromyography. In thecase of the internal biometric feature, the biometric sensor may be acommon thermometer, a cardiotachometer, a blood glucose meter, a caloriemeter, and the like, for capturing the internal biometric features ofthe body temperature, the cardiac rate, the blood glucose content, thevena state, and the calorie consumption, etc., respectively. In theelectronic apparatus 100, the biometric capture unit 106 may be used tocapture the biometric feature simply, and store them in the electronicapparatus 100 or display them to the user through the first play unit,such as a display.

More particularly, in the case where the biometric feature is theelectromyography, a muscle motion may be detected by theelectromyography. For example, a skin may be measured by the sensorbuilt in the system to detect the electromyography, and then the actionparameters of the hands and the fingers of the user are obtained, andthe motion parameters of the hands and the fingers of the user are knownin conjunction with other sensors, e.g., an acceleration sensor, builtin the system. Synthesizing those two types of parameters, an actionmade in the air by the hands of the user with a gesture or hand form isknown for an interactive control of the local apparatus or otherapparatus.

In the case where the biometric feature is the calorie consumption, thesensor, e.g., an acceleration sensor, built in the system may be used toacquire a motion condition of the user, analyze a statistic calorieconsumption, monitor the motion condition and adjust a workout plan bycooperating with the user effectively.

Furthermore, those biometric features may be acquired dedicatedly, thatis, independently of a step by which an interactive control operationinput by the user is received therefrom by an operation input unit, anda single acquisition process is required for the biometric capture unit106 to acquire the biometric features.

Alternatively, those biometric features may be operating while beingacquired, that is, the biometric features are acquired through anacquisition process by that biometric capture unit 106, while theinteractive control operation input by the user is received therefrom bythe operation input unit. Thus, the control input and the biometricacquisition may be conducted synchronously, and twice operations are notrequired, even the user may be made to complete the biometricacquisition without any consciousness, which eliminates successfully adanger (fear) of difficulty occurred when the biometric features areacquired by the user individually.

To this end, the electronic apparatus 100 further comprises an operationinput unit set on at least one of the body device and the holdingdevice, which is used to obtain an interactive control operation inputby the user to generate a first operation input signal, and while theinteractive control operation is obtained by the operation input unit,the first biometric feature information is obtained by the biometriccapture unit 106, and the processing unit generates a first controlsignal according to the first operation input signal and controls theelectronic apparatus to perform the first control signal. For example,the operation input unit may be any type of input unit, such as thesensing unit, the image capture unit, the sound capture unit asdescribed above, or a simple mouse, a keyboard, or a keypad, etc.

The operation input unit and the biometric capture unit may also be asingle unit integrated together with each other. Alternatively, theoperation input unit and the biometric capture unit may also be separatetwo units.

In the first implementation, it is assumed that the operation input unitis a touch screen and the biometric capture unit is an iris camera, thenin the smart watch 100, the iris camera in the visible region of theeyes of the user may be activated while the touch screen is used by theuser to plot an interactive gesture for controlling the smart watch, andthe iris camera is made to capture an iris image of the user as thebiometric information for storage, display, or other usage.

The operation input unit and the biometric sensor may be the samedevice.

In the second implementation, it is assumed that the operation inputunit is the touch screen and the biometric capture unit is also thetouch screen, then in the electronic apparatus 100, a fingerprint of thefinger by which an interactive gesture is plotted by the user mayrecognized by the touch screen, and the fingerprint is recognized, whilethe interactive gesture is plotted by using the touch screen by the userto control the smart watch.

After the biometric features are captured, in addition to a simplestorage and display of them, the biometric features may also be used toauthenticate the operations of the user for providing a safety of theelectronic apparatus 100.

To this end, before the electronic apparatus is controlled by theprocessing unit to perform the first control signal, the processing unitobtains a reference biometric information, decides whether the firstbiometric information matches the reference biometric information, andobtains a first decision result, and controls the electronic apparatusto perform the first control signal if the first decision resultindicates that the first biometric information matches the referencebiometric information.

Thereby, in the first and second implementation as described above,after the first biometric information, such as the iris and thefingerprint, of the user is obtained, the smart watch may determinewhether the current user has the right to control the electronicapparatus to perform the operations desired by using the first biometricinformation to compare with the reference biometric information.

In that case, the reference biometric information may be stored in alocal memory, such that the entire authentication procedure is able tobe completed locally and quickly. Alternatively, the reference biometricinformation may also be stored at the remote, e.g., a cloud server, inorder to save the storage space in the smart watch, at that time, theelectronic apparatus 100 comprises a communication unit for downloadingthe reference biometric information from the remote, so as to ensurethat the operation is able to be authenticated locally in advance.Alternatively, the communication unit may be used to send the firstbiometric information to the cloud server, causing the authenticationoperation for the information comparison to be completed at the cloud,and used to receive a result of the authentication from the cloudserver, such that the processing unit 103 determines how to make aresponse.

As noted above, the biometric information may include the internalbiometric information of the user, such as the electromyography, thebody temperature, the cardiac rate, the blood glucose content, the venastate, and the calorie consumption, etc. At this point, a biometricsensor may be located in the housing unit or the holding unit, and maycontact directly with the skin or separate from the skin by a distance.And, the biometric sensor may be various different types of sensors formonitoannular a human medical parameters, seveannular to the physicaland psychological health of the user.

FIG. 8 is the side view illustrating the configuration example of abiometric capture unit of the electronic apparatus in accordance with afourth embodiment of the disclosure.

As described above, when the biometric information is an informationassociated with the internal biometric of the user, an acquisitiondirection of the biometric capture unit is in the inward direction ofthe annular or the approximated annular space. For example, thebiometric capture unit 106 may be arranged at a position where the smartwatch contacts with the body of the user physically, in particular,arranged on a position with which the interior of the smart watch of thewrist of the user is able to be contacted, in order to serve as anelectromyography sensor for capturing an electromyography, a commonthermometer, a cardiotachometer, a blood glucose meter, a blood pressuremeter, a calorie meter, and the like for capturing a body temperature, acardiac rate, a blood glucose content, a vena state, and a calorieconsumption, etc., respectively, as shown in FIG. 8.

Furthermore, the biometric information may include the externalbiometric information of the user. The position at which the biometriccapture unit is located in electronic apparatus when the biometricinformation is the external biometric information will be depicted withreference to the configuration example hereinafter.

In the first configuration example, the biometric capture unit comprisesa sensing unit for sensing a sense control operation generated by theoperating object touching or near touching the sense region to generatea first sense signal, and obtaining the first biometric informationaccording to the first sense signal.

That is, such biometric sensor may be a touch screen for capturing thefingerprint and/or the palm print of the user. The touch screen maycapture the related information when the user places finger (or palm) onthe touch screen in order to input the fingerprint (or the palm print)simply; and may also capture the related information when the userpresses finger on the touch screen in order to perform a click operationor slides finger on the touch screen in order to perform a slidingoperation.

The position where the sensing unit is located in the electronicapparatus can be seen in the related conditions as described withreference to FIGS. 5A to 5G in the first embodiment as describe above.

Moreover, in the second configuration example, the biometric captureunit comprises an image capture unit for capturing an action controloperation generated by the operating object to generate a first imagecapture signal, and obtaining the first biometric information accordingto the first image capture signal.

That is, such biometric sensor may be a camera for capturing thefingerprint, the palm print, and/or the iris of the user. The camera maycapture the related information when the user aligns the finger, thepalm, and/or the eyeball with the camera in order to input thefingerprint, the palm print, and/or the iris simply; and may alsocapture the related information when the user presses finger or blinks,etc., in order to perform a click operation or moves the finger orrotates the eyeball, etc., in order to perform a sliding operation.

The position where the image capture unit is located in the electronicapparatus can be seen in the related cases as described with referenceto FIGS. 7A to 7G in the second embodiment describe above.

Moreover, in the third configuration example, the biometric capture unitcomprises a sound capture unit for capturing a sound control operationgenerated by the user to generate a first sound capture signal, andobtaining the first biometric information according to the first soundcapture signal.

That is, such biometric sensor may be a microphone for capturing thesound print of the user. The microphone may capture the relatedinformation when the user speaks a sentence casually in order to inputthe sound print simply; and may also capture the related informationwhen the user speaks a name of a menu button in order to perform certainmenu selection operation.

The position where the sound capture unit is located in the electronicapparatus can be seen in the related cases as described in the thirdembodiment describe above.

The processing unitgenerates a first control signal according to the first operationtrigger signal, and controls the electronic apparatus to perform thefirst control signal.

For example, the distance detection unit 106 may be an proximity sensorfor deciding a distance between the object and the electronic apparatus,enabling the processing unit 103 to trigger the electronic apparatus toperform different operations according to different distances therebetween.

FIGS. 9A to 9C are block diagrams illustrating the structure of theelectronic apparatus in accordance with the fifth embodiment of thedisclosure.

In addition to the first display unit 104, a second display unit 105 isalso arranged on the body device 101, as shown in FIGS. 9A to 9C. Theprocessing unit 103 is utilized to generate an image to be displayed andperform a display control. The second display unit 105 is utilized tooutput a second image. More particularly, the second image generated bythe processing unit 103 is output by the second display unit 105 underthe display control performed by the processing unit 103. The seconddisplay unit 105 is arranged on the body device 101 in the electronicapparatus 100 shown in FIG. 9A. However, it is appreciated readily bythose skilled in the art that the disclosure is not limited thereto. Forexample, for example, the second display unit 105 may also be arrangedon the holding device 102 in the electronic apparatus 100 shown in FIGS.9B and 9C.

The second display unit 105 is a display unit complying with variousdisplay principles. For example, the second display unit 105 may be aconventional optical display system comprising, but not limited to, aliquid crystal display unit, an organic electroluminance display unit,an organic light-emitting diode display unit, an E Ink type of displayunit, and the like. The second display unit 105 is a display unit 104 ofwhich the type is different from that of the first display unit.

More particularly, the second display unit 105 may comprise a secondvisible portion 1051 which is a portion viewed by the user so as toperceive or see a displayed content in the second display unit 105. Thatis, the second display unit 105 as described below contains a pluralityof members depending on the principle thereof, and wherein the secondvisible portion 1051 is a region in which a display of the image contentis observed actually by the user. At this point, a position of thesecond display unit 105 described above may in fact refer to theposition of the second visible portion 1051.

The different configuration examples of the first and second visibleportion will be depicted with reference to FIGS. 10A to 10F hereinafter.

Returning to FIGS. 9A to 9C, the configuration of the distance detectionunit 106 is further depicted.

The distance detection unit 106 is utilized to detect the first distancebetween the object and the distance detection unit, and generate thefirst operation trigger signal according to the relative relationshipbetween the first distance and a threshold distance. The processing unit103 generates a first control signal according to the first operationtrigger signal, and controls the electronic apparatus to perform thefirst control signal, wherein when the relative relationship indicatesthat the first distance is less than or equal to the threshold distance,the first control signal is used to cause the electronic apparatus toturn off the display of the second display unit and turn on the displayof the first display unit under the control of the processing unit; orwhen the relative relationship indicates that the first distance isgreater than the threshold distance, the first control signal is used tocause the electronic apparatus to turn off the display of the firstdisplay unit and turn on the display of the second display unit underthe control of the processing unit.

That is, in the case where it is assumed that the near-to-eye display isin the dial portion of the smart watch, when the proximity sensordetects that the user moves to approach the dial portion of the smartwatch, it is decided that the user desires to use the near-eye display,at this point, the near-eye display may be enabled, and the commondisplay is turned off, in order to save the energy consumption.Conversely, when the proximity sensor detects that the user moves awayfrom the dial portion of the smart watch, it is decided that the userdesires to use the common display, at this point, the common display maybe enabled, and the near-to-eye display is turned off, in order to savethe energy consumption. That is, different display units may be switchedto a work state by the smart watch according to the distance between thehuman body and the electronic apparatus detected by the proximitysensor.

To this end, the proximity sensor may simply emit a light outwardly anddetect whether a returned light is able to be emitted by the user, andmakes a decision about which the user has approached the near-to-eyedisplay when the emitted light is capable of being detected, andgenerates a switch display trigger signal.

Alternatively, the proximity sensor may detect an absolute distancebetween the user and the near-to-eye display directly in other ways,compares the absolute distance with one preset threshold, and generatesthe switch display trigger signal when it is detected that the absolutedistance is changed from a value less than the preset threshold to avalue greater than the preset threshold or from a value greater than thepreset threshold to a value less than the preset threshold.

Apparently, in order to complete the operation as described above, thedistance detection unit and the first visible portion are set in thesame region, for example, both of them may be set a first region wherethe first visible portion 1041 of the first display unit 104 is located.
